For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figure 1 An embodiment of the utility model provides a parking brake bracket clamp, including: a base 10, a plurality of clamping mechanisms 20 and an angle positioning mechanism 30.

[0030] A positioning seat 11 is disposed on the base 10 , and a positioning stopper 12 is disposed on the positioning seat 11 . The positioning stopper 12 is used for positioning and cooperating with the inner wall of the hole of the workpiece 50 .

[0031] See also Figure 2, multiple clamping mechanisms 20 are set on the base 10 and arranged on at least two sides of the positioning seat 11, wherein the clamping mechanism 20 includes a lower pressure piece 21 and a first lifting drive assembly 22, the first lifting drive assembly 22 is set on the base 10 and is drivingly connected to the lower pressure piece 21, the lower pressure piece 21 can be lifted and lowered above the positioning seat 11, and is used to press the workpiece 50 to the top of the positioning seat 11; the angle positioning mechanism 30 includes a side pressure block 31 and a translation drive assembly 32, the side pressure block 31 is movably set on one side of the positioning seat 11, the translation drive assembly 32 is set on the base 10, and is drivingly connected to the side pressure block 31, and is used to drive the side pressure block 31 to press the workpiece 50 to the positioning stopper 12.

[0032] Since a nearly semicircular hole is formed on the workpiece 50, if the workpiece 50 is pressed from both sides of the workpiece 50, the parts of the workpiece 50 located on both sides of the hole are easily deformed into the hole. In the present invention, after the workpiece 50 is placed on the positioning seat 11, the positioning block 12 directly extends into the hole of the workpiece 50 and abuts against the inner wall of the hole of the workpiece 50. Then the side pressure block 31 presses the workpiece 50 against the positioning block 12, so that the angle of the workpiece 50 is positioned, and the positioning block 12 can effectively avoid the deformation of the workpiece 50 and improve the positioning stability. Then, the lower pressing piece 21 is lowered to press the workpiece 50.

[0033] The specific structure of the first lifting drive component 22 can be designed according to actual needs. For example, in some optional embodiments, the first lifting drive component 22 includes a first screw 221, a limit block 222 and an elastic member 223. The first screw 221 is arranged on the base 10, and the limit block 222 is threadedly matched with the first screw 221. A through hole is provided on the pressing member 21. The pressing member 21 is movably sleeved on the first screw 221 through the through hole, and is located between the limit block 222 and the base 10. The elastic member 223 is arranged between the pressing member 21 and the base 10. The elastic force of the elastic member 223 pushes the pressing member 21 upward against the limit block 222. When the limit block 222 descends along the first screw 221, it can drive the pressing member 21 to be pressed downward.

[0034] Of course, the structure of the first lifting drive assembly 22 is not limited to this. Technical personnel in this field can also select other suitable structures according to the teachings of the present utility model. The first lifting drive assembly 22 can be a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly or a linear motor translation drive assembly.

[0035] Since the limit block 222 is tightened manually, there may be an uneven descending position of the pressing pieces 21 on both sides of the workpiece 50, resulting in uneven pressure on both sides of the workpiece 50. For this reason, in some optional embodiments, multiple clamping mechanisms 20 are evenly arranged on the opposite sides of the positioning seat 11, wherein a vertical guide hole 113 is provided on the positioning seat 11, and the first screw 221 extends to the bottom of the positioning seat 11 after passing through the vertical guide hole 113, and at least one balance rod 13 is provided at the bottom of the positioning seat 11, and the two ends of the balance rod 13 are respectively rotatably matched with the first screw 221 on both sides of the positioning seat 11, and a protruding support portion 131 is provided on the top of the balance rod 13, and the support portion 131 is movably abutted against the bottom of the positioning seat 11.

[0036] The supporting portion 131 is equivalent to the fulcrum of the lever, and the two ends of the balance bar 13 are equivalent to the lever. After each limit block 222 descends along the first screw 221 until the pressing piece 21 is driven to press against the workpiece 50, if the limit block 222 on one side continues to rotate, it will drive the first screw 221 to rise, so that one end of the balance bar 13 rises, and the other end of the balance bar 13 will descend, thereby driving the first screw 221 on the other side to descend, so that the limit block 222 on the other side also descends and drives the pressing piece 21 on the other side to press down. At this time, it is equivalent to the limit block 222 on one side driving the pressing pieces 21 on both sides to press down the workpiece 50 at the same time, so as to achieve uniform downward pressure, avoid excessive pressure on one side of the workpiece 50, and improve the positioning stability of the workpiece 50.

[0037] When the support rod swings, the support portion 131 will also rotate relative to the bottom of the positioning seat 11 and change its angle. In some optional embodiments, the top surface of the support portion 131 is an arc-shaped surface, which can enable the rotation axis of the support portion 131 to maintain a distance from the positioning seat 11.

[0038] In this embodiment, the positioning seat 11 includes a positioning portion 111 and a mounting plate 112. The positioning portion 111 is installed on the base 10 through the mounting plate 112. The vertical guide hole 113 and the clamping mechanism 20 are arranged on the mounting plate 112 and are located on both sides of the positioning portion 111. The support portion 131 abuts against the bottom of the mounting plate 112.

[0039] See also Figure 3 and Figure 4In some optional embodiments, the parking brake bracket clamp also includes: an auxiliary support mechanism 40, the auxiliary support mechanism 40 includes a support block 41 and a second lifting drive assembly 42, the second lifting drive assembly 42 is arranged on the base 10 and is drivingly connected to the support block 41, and a lifting groove 114 is provided on the positioning seat 11, the support block 41 can be lifted and lowered in the lifting groove 114, and is correspondingly located directly below one of the lower pressing pieces 21, for pressing the workpiece 50 toward the lower pressing piece 21. After the workpiece 50 is placed on the positioning seat 11, the positioning stop block 12 abuts against the inner wall of the hole of the workpiece 50. At this time, the corresponding pressing piece 21 above the support block 41 is lowered, so that the corresponding pressing piece 21 lightly presses the workpiece 50 to achieve preliminary positioning, and then the side pressure block 31 presses the workpiece 50 toward the positioning stop block 12, and then the other pressing pieces 21 are lowered to clamp the workpiece 50, and then the support block 41 is raised to press the bottom of the workpiece 50, and then the corresponding pressing piece 21 above the support block 41 is moved downward to clamp the workpiece 50. The support hole and the corresponding pressing piece 21 can stably clamp the workpiece 50, thereby further improving the stability of the workpiece 50 and facilitating the preliminary positioning of the workpiece 50 during the clamping process.

[0040] The specific structure of the second lifting drive assembly 42 can be designed according to actual needs. For example, in some optional embodiments, the second lifting drive assembly 42 includes a second screw 421 and a driving block 422. The second screw 421 is threadedly matched with the base 10, and the driving block 422 is connected to the second screw 421. A driving inclined surface is provided on the driving block 422. A guiding inclined surface that slides with the driving inclined surface is provided at the bottom of the support block 41. When the second screw 421 is translated, the driving inclined surface slides along the guiding inclined surface and drives the support block 41 to rise and fall. Since there are structures such as the pressing piece 21 above the support block 41, the arrangement space of the second lifting drive assembly 42 is limited. Therefore, based on the principle of the inclined wedge mechanism, the driving block 422 changes the direction of the force through the driving inclined surface and the guiding inclined surface, so that the second screw 421 can drive the support block 41 to rise and fall by horizontal movement. The second screw 421 can be arranged on one side of the positioning seat 11 to facilitate driving the support block 41 to rise and fall.

[0041] Of course, the structure of the second lifting drive assembly 42 is not limited to this. Technical personnel in this field can also select other suitable structures according to the teachings of the present invention. The second lifting drive assembly 42 can be a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly or a linear motor translation drive assembly.

[0042] In some optional embodiments, a plurality of positioning blocks 12 are provided on the positioning seat 11 , and the plurality of positioning blocks 12 are arranged in sequence along a direction surrounding a preset center point, so as to facilitate stable positioning of the workpiece 50 .

[0043] See also Figure 5 In some optional embodiments, an adjustment slot 14 is provided on the positioning seat 11, and the adjustment slot 14 extends in a direction close to a preset center point. The positioning block 12 is movably arranged in the adjustment slot 14, and the preset center point is located on the central axis of the hole of the workpiece 50. Different workpieces 50 have different hole sizes. The positioning block 12 can adapt to workpieces 50 of different sizes by fine-tuning its position along the adjustment slot 14.

[0044] In some optional embodiments, an adjusting screw 15 is provided in the adjusting groove 14, and an adjusting block 16 is provided on the adjusting screw 15. The adjusting block 16 is threadedly matched with the adjusting screw 15 and abuts against the side of the positioning block 12 away from the side pressure block 31. The adjusting block 16 moves along the adjusting screw 15 in a direction away from or close to the preset center point, thereby adjusting the position of the positioning block 12. When the side pressure block 31 presses the workpiece 50, the pressure from the side pressure block 31 is transmitted to the limit block 222 after passing through the workpiece 50 and the positioning block 12.

[0045] In some optional embodiments, two protruding clamping portions 311 are provided on the side pressure block 31, and an avoidance groove 312 is formed between the two clamping portions 311. The avoidance groove 312 is used to avoid some protruding structures of the workpiece 50. A positioning plane is formed on the side of the clamping portion 311 facing the positioning block 12. The positioning planes of the two clamping portions 311 can better position the angle of the workpiece 50 and improve the angle positioning stability.

[0046] The specific structure of the translation drive assembly 32 can be designed according to actual needs. For example, in some optional embodiments, the translation drive assembly 32 includes a sliding seat 321 and a driving screw 322. The sliding seat 321 is slidably disposed on the base 10. The driving screw 322 is threadedly engaged with the base 10 and is connected to the sliding seat 321. The side pressure block 31 is disposed on the sliding seat 321. When the driving screw 322 rotates, the sliding seat 321 can be driven to move, thereby driving the side pressure block 31 to approach or move away from the positioning block 12.
